What is the black residue that appears in my sinks overnight?
redheadednowhere asked:
It appears to be coming from the drains as its the darkest and most concentrated closest to the drains. When we leave town we return to find our sinks simply filled with it– it looks like someone poured dark candle wax down the sinks. If I plug the sink with the stopper… There’s no residue in the morning. Very odd. It wipes up easily with 409 and a paper towel. Any ideas?
